The Wisconsin Academy of Sciences, Arts and Letters will observe the 10th anniversary of the terrorist attacks of 9/11 on Sunday, September 11, 2011, with an afternoon of discussion and reflection. "Perspectives on a Post-9/11 World" brings together a diverse group of distinguished historians, political scientists, artists, musicians, and writers to reflect on questions surrounding who we have become as a nation and as a people in an age of global terrorism, liberation movements, technological upheavals, economic insecurity, and fractious politics. "Islam and America: Citizenship and Democracy" features Charles Cohen, UW-Madison professor of history and religious studies and director of the Lubar Institute for the Study of Abrahamic Religions; Louise Cainkar, associate professor in the Department of Social and Cultural Sciences, Marquette University, and author of Homeland Insecurity: The Arab American Experience after 9/11; and Asifa Quraishi, assistant professor of law at UW-Madison, reflecting on the meaning of citizenship in America.
